Ok, so basically what I thought. Whats the average run of an evo8 mani tho? any suggestions on brand? Although it sounds like an awesome idea running an evo8 mani/turbo on the 420a. Price is a factor aswell. I know a good log manifold for the 420 will land me between $225-$275 brand new. Turbo, depending on whether I go new or used will obviously vary between let's say $300-$550. Depending on brand/shaftplay/size/etc/etc....
